Hello came here there is everyone say that my eGPU is working perfectly thanks to the help nando, had it not been he had not been able to run my eGPU by the generation of DSDT config file which was done by nando 😛

@max_dar, RX580 works great on a mPCIe interface shown by @Decio_neto here, or on expresscard as seen in my signature. Do follow that link to see benchmarked performance as well as an explanation on how to enable eGPU accelerated internal LCD mode.
